摘　　要：以甘塔斯隧道工程为例,详细分析了不同围岩条件地段的施工技术,包括高地应力地段的变形评估与多层拱架分次施工,富水地段的排水与支护措施,斜井进入正洞的挑顶施工技术,以及横通道的开挖与支护。研究结果表明,针对隧道地质条件采用爆破暗挖法、掌子面预加固技术、多层拱架分次施工技术等,可有效控制围岩变形与坍塌。通过合理的设计和施工技术,有效保障了隧道施工的安全和质量。Taking Gantas Tunnel project as an example,the construction technology of different surrounding rock conditions is analyzed in detail,including deformation assessment and multi-layer arch construction in high ground stress area,drainage and support measures in rich water area,roof lifting construction technology for inclined shaft entering positive hole,and excavation and support of cross passage.The results show that the deformation and collapse of surrounding rock can be controlled effectively by using blasting excavation,pre-reinforcement technology of the face of the face and multi-layer arch construction technology according to the geological conditions of tunnel.Through reasonable design and construction technology,the safety and quality of tunnel construction can be effectively guaranteed.
